Keep in mind that counties (even cities, if school districts are seperated that way) have big differences across (even adjacent) school districts.
Schools have differences, also. Pick the right school, if you are able to pick one, or else you'll end up with a bunch of idiots. You should consider private school if you can afford it.
Check reviews for schools. That way, you will hopefully not be in an environment full of idiotic people, and you'll be in an environment with less idiots. I go through being with idiots and it will tear you apart if you are too different.
